A koala is sitting up a gumtree smoking a joint when a little lizard walks past, looks up and says:

"Hey Koala, what are you doing?"
The koala says: "Smoking a joint.
Come up and have some."

So the little lizard climbs up, sits next to the koala
and they enjoy a large doobie.
After a while the little lizard says his mouth is dry
and he is going to get a drink from the river.

But the little lizard is so stoned that he leans too far over and falls into the river.
A crocodile sees this, swims over to the little lizard and helps him to the side then asks the little lizard:
"What's the matter with you?"

The little lizard explains to the crocodile that he was sitting smoking a joint with the koala in the tree, got too stoned and then fell into the river while taking a drink.
